If you want to eliminate gas permeation and gas release with a vacuum rubber O-ring, replace it with a spring-energized C-ring! 'Delta Beta HNRV'

"Replace rubber O-ring to metal seal, Eliminate gas permeation and gas release." This can be possible with Delta Beta HNRV.

The Delta Beta HNRV(low load type HELICOFLEX) is originally designed with a low design tightening pressure (Y) and a special processing of the internal spring, achieving replacement of rubber O-rings, performance enhancement, and PFAS-free characteristics. It is a metal seal recommended for those who have concerns such as: "I want to eliminate gas permeation and gas release from vacuum rubber O-rings." "I cannot change the number or size of bolts on existing flanges." "I am troubled by PFAS in rubber O-rings." 【Features】 ■ Mainly for ultra-high vacuum ■ Even lower design tightening pressure than before ■ Can be replaced with elastomer O-rings ■ Two delta-shaped protrusions on the contact side of the cross-section ■ PFAS-free This does not guarantee compatibility with existing flanges. Specifications for existing flanges are required. For more details, please download the PDF or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
